Preheat the oven to 375 degrees. Line a sheet pan with parchment paper. Slice the ham and arrange it on one third of the pan, slightly overlapping. Place the peeled carrots on the second section and the potatoes on the remaining section. In a mason jar or lidded container, combine the olive oil, vinegar, marmalade, diced shallot, Fleur de Sel, and minced garlic, then shake well until fully combined. Pour the glaze evenly over the ham, carrots, and potatoes. Roast for 30 minutes. Remove from the oven and carefully drain the pan juices into a heat safe bowl to drizzle over each serving. Garnish with fresh parsley and serve.
